Open cut underground passage adjacent subway station supporting and reinforcing construction method
The invention discloses an open cut underground passage adjacent subway station supporting and reinforcing construction method, and particularly relates to the technical field of underground passage construction. The method comprises the following steps of S1, preparation before construction: construction measurement datum points are determined, and a construction region is determined; S2, supporting and reinforcing: firstly, one side, parallel to a subway shield region, of an underground passage is supported through support piles and inner support, then, the upper side of the subway shield region is supported through a grouting reinforcing region and anti-floating piles, next, the underground passage and a subway station are reinforced through a cement soil retaining wall, and then, slope excavation is performed; and S3, underground passage construction and soil covering backfilling. The open cut underground passage adjacent subway station supporting and reinforcing construction method has the advantages that through the supporting and reinforcing, the construction of the underground passage by an open cut method is convenient, the construction difficulty is reduced, the construction period is shortened, the construction cost is reduced, and meanwhile, the safety in the underground passage construction process is improved.
本发明公开了一种明挖地下通道紧邻地铁车站支护加固施工方法，尤其是涉及地下通道施工技术领域，其包括以下步骤：S1、施工前准备：施工测量基准点的确认以及施工区域的确定；S2、支护加固：首先通过支护桩和内支撑支护对地下通道与地铁盾构区间平行一侧进行支护，然后通过注浆加固区和抗浮桩对地铁盾构区间上方进行支护，再通过水泥土挡墙对地下通道和地铁车站之间进行加固，然后进行放坡开挖；S3、地下通道的施工以及覆土回填。本发明的明挖地下通道紧邻地铁车站支护加固施工方法，通过支护加固，便于使用明挖法进行地下通道的施工，降低施工难度，缩短施工周期，降低施工成本，同时，提高地下通道施工过程中的安全性。
